Definitions

  • This invention relates to a process and apparatus for the production of fibrous blends consisting of fiber batches that have two or more different colors and that are made by the Vigoureux dyeing method and/or by solid-color dyeing.
  • Blends are composed of fiber slivers, such as combed sliver consisting of wool or cotton, or of fiber strands of synthetic fibers, e.g. polyester or polyacrylonitrile, in varying colors and with specific color patterns.
  • the fiber batches necessary to obtain a desired combination have heretofore been produced by a discontinuous process. This holds true for the batches of solid-dyed slivers, and particularly for the batches made by the Vigoureux printing method for which special machines have been developed. It will be understood that in the Vigoureux printing method slivers, particularly wool slivers, are printed to provide a mixed color effect therein.
  • the combed slivers to be imprinted first pass, coming from a reel-off frame, through a printing machine wherein the slivers are initially made into a thin fibrous fleece by means of a simple needle field.
  • This fleece then passes through a printing roller system, after which it is seized and gathered by a sliver depositing device and is then laid into baskets or the like.
  • the printing machine consists of a dipping roller which transfers ink to a felt-covered delivery roller. The actual printing rolls rest, under load, on the delivery roller and press, in accordance with their profiles, the passing fleece against the delivery roll, thus wetting the fleece with ink along a larger or smaller area transversely across the operating width.
  • the dye deposited or printed sliver enters a steaming device in order to fix the dye, wherein the steaming process takes 1 to 3 hours, depending on the type of dye employed.
  • the slivers After cooling, the slivers pass through a dye back washer in order to free the slivers of excess dyes and chemicals. Subsequently, the slivers must be dried.
  • the conventional manner of producing blends is very time consuming and requires a large number of man hours with concomitant expenses for wages.
  • the invention is based on the problem of developing a process and apparatus which makes it possible to continuously produce in a single operating step any desired blend composed of solid-color fibrous components or mixtures thereof and/or of the Vigoureux fibrous components, so that the customary mixing processes prior to the drawing step, are eliminated.
  • the drawing step is still necessary.
  • the dyes or pastes can be of any desired character.
  • the colorants can also consist of a mixture containing heavy metal salts or optical brighteners, or also resist agents, so that any desired subsequent effect can be printed on the slivers or strands.
  • the printing pattern can advantageously be applied at least on a portion of the strands traveling together through the apparatus in the transverse direction with a certain color pattern and then, by means of a further printing means, with another color and another pattern.
  • individual slivers can also be dyed in a solid color and can then be further treated together with the imprinted slivers.
  • effective fibrous blends can be produced, without having to combine individual prefabricated batches into a blend.
  • a desired blend can be predetermined for one machine run, which blend is then finally formed, after the customary, but presently continuously conducted treatment steps, with the aid of a conventional drawing device.
  • the known Vigoureux printing machine is not very well suitable for the heretofore described process.
  • the forced contact of the necessarily thin fibrous fleece against the dye-impregnated felt bottom roll also has the disadvantage that the thus-obtained prints have differing color depths with an increasing operating time, due to changes in the properties of the felt roll.
  • the production of the thin fleeces for an entire blend batch is too complicated. It is more advantageous for the process of this invention if the material to be imprinted -- independently of the time period for which the roll operates or the running length of the machine -- is always provided with a constant amount of dye which also satisfactorily imprints combed sliver or synthetic fiber slivers. This is made possible, in a further development of the process of this invention by transferring to the slivers or the like, preferably on both sides, an always constant amount of ink or paste from indentations in at least one intaglio cylinder.
  • FIGS. 1A and 1B show the apparatus.
  • the fiber strands or the like necessary for producing a blend batch are withdrawn from the cans or containers 1 and together are fed in parallel relationship to a printing and/or dyeing system, connected thereafter.
  • This system consists essentially of the Vigoureux printing machine 2 which, according to the drawing, is equipped with three pairs of printing rolls 3.
  • the individual rolls of the printing roll pairs 3 are made of steel and have a polished surface. Patterns are engraved in this surface in a conventional manner, and these patterns are filled with inks or pastes with the aid of scrapers 4.
  • the lower roll 5 of each pair of rollers automatically absorbs the ink from a trough 6.
  • the scraper 4 associated with this roll smooths out the ink received within the engravings.
  • the dye is fed into a slot between the roll and the scraper.
  • the top roll as well as the bottom roll of a printing roll pair 3 can imprint on the passing fibrous material a different pattern with the respectively desired color; in each individual case -- independently of the operating length of the printing unit -- a constant amount of ink is always offered to the material and absorbed thereby.
  • a padder or dyeing unit 8 is arranged, with the aid of which individual fiber slivers or strands can also be dyed with a solid color.
  • the path of these slivers is shown in dashed lines. After the dyeing step, these slivers travel above the printing machine 2, so that the printing rolls are not unnecessarily stressed and contaminated.
  • the subsequent sieve drum dryer 14 having several sieve drums 15 under a suction draft, dries the material and transports it immediately in the direction toward a depositing means 16 or, previously, to a mixing gill box machine or mixing zone not illustrated in detail and denoted by reference numeral 17.
  • this mixing zone consists of several intersecting heads; the strands exiting therefrom are combined, laterally withdrawn and then drawn as a wide band from a collective drawing unit. The process takes place before processing in the initial spinning device when several differently colored combed slivers are to be mixed in order to obtain a desired colored hue.
  • the above-described plant produces automatically, without a large number of operating personnel, any desired batch for a blend.
  • the number of slivers to be imprinted or to be dyed and also the printing pattern with the respective ink are determined.
  • the bundle of continuous strands can immediately be fed to the drawing unit, so that, in addition to obtaining the advantages of a continuous plant, the present invention also saves the space and the machine unit for the customary mixing processes.
